ORA-12705 invalid or unknown NLS parameter value specified

Cause: There are two possible causes: Either an attempt was made to issue an ALTER SESSION statement with an invalid NLS parameter or value; or the NLS_LANG environment variable contains an invalid language, territory, or character set.

Action: Check the syntax of the ALTER SESSION command and the NLS parameter, correct the syntax and retry the statement, or specify correct values in the NLS_LANG environment variable. For more information about the syntax of the ALTER SESSION command, see Oracle8i SQL Reference.

You try to remove the environment variable NLS_LANG. Then log again.

I had a similar issue and deleting NLS_LANG solved the problem.

Where exactly do I have to delete NLS_LANG under ORACLE folder in the registry or is it in more then one location.

Hi,
if your getting Ora-12705 error then unset NLS_LANG parameter.


on linux
export NLS_LANG=

on windows
set NLS_LANG=

Taj

In the registry.
In environment variables.

Try this...
check if exist into windows registry (regedit) the oracle_home
Example
[HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE]
ORACLE_HOME=D:\Appls\Oracle
if not create one.

and add the path into the windows variable PATH adding bin folder
example D:\Appls\Oracle\bin
Control Panel -> System -> Advanced Options -> Environment variables - > system variables -> path
